Hello i have a 150g salt tank with 2 fluval 403's for filter. after reading so much on this site i have decided that these suck lol and want to go to sump/refugium from aquauniverse. I am looking at the one for 300g tanks looks to be a 40gallon sump with about 1000gph on pump, any feedback on aquauniverse or these sumps would be appreciated thx
